In each step the LZSS algorithm sends either a character or a pair. Among these, perhaps character "e" appears more frequently than "x", and a pair of length 3 might be commoner than one of length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.-In each step the LZSS algorithm sends either a character or a lt;position, lengthgt; pair.

给定若干个字符及其对应的权重,建造一颗高度尽可能小的Huffman树及字符的Huffman编码。-given a number of characters and their corresponding weights, construction of a high as possible Huffman tree and the character of Huffman coding.
我发现这个网站上缺少关于3D-SPIHT编码。这个是我收集的3D-SPIHT,也是来自于Pro.Peraman的官网。 可以用来做实验,写论文。希望对大家有用。-i found that the website lack of 3d-spiht coding, this 3d-spiht coding is from websites of Pro.Pearlman. i hope it is useful for you.
